The original release of the Silencer MK III series came last year, but more recently PC Power & Cooling has done another round of revisions on this series which introduced some notable upgrades. Energy efficiency was taken from an 80PLUS Bronze certification right up to 80PLUS Gold, fan size was increased to a 140mm fan which should offer better efficiency and lower noise, the modular cable design was given a screw-on steel design, and among some other smaller changes, the warranty was increased to seven years."
